sha256_fhe

This repo contains the implementation of a homomorphic sha256 function. In other words, a function that computes a sha256 hash over encrypted data such that H(E(Data)) = E(H(Data)). Hence the server that does the computation doesn't know at all the input data nor the resulting hash.

This program should be run with cargo run --release.

Make sure to add the correct dependency to the Cargo.toml file depending on your computer architecture:

tfhe = { version = "0.2.x", features = ["boolean", "x86_64-unix"] }

tfhe = { version = "0.2.x", features = ["boolean", "aarch64-unix"] }

For a detailed explanation of our homomorphic sha256 implementation you can read this tutorial.
